What would an echo stress test show....That a regular echo test doesn't?

Change w/exercise : When excercised, or 'stressed', the heart needs more oxegen to function properly than at rest. If it's not getting that increase, the muscle will start to move in abnormal ways, which will show up on the echo. At rest, because it needs less oxegen, it may be getting enough, so it will look normal then. ...Read more

Stress (Definition)

Stress affects most people in some way. Acute (sudden, short-term) stress leads to rapid changes throughout the body. Almost all body systems (the heart and blood vessels, immune system, lungs, digestive system, sensory organs, and brain) gear up to meet perceived danger. These stress responses could prove beneficial in a critical, life-or-death situation. Over time, however, repeated stressful situations put a strain on the body that may contribute to physical and psychological problems. Chronic (long-term) stress can have real health consequences and should be addressed like any other health concern. Fortunately, research is showing that lifestyle changes and stress-reduction techniques can help people learn ...Read more

How accurate is a stress echo test? Checking.For heart disease and blockages ? Is it efficient ?

How accurate is a stress echo test? Checking.For heart disease and blockages ? Is it efficient ?

A good test: But it is only suggestive and cannot tell you whether you have any coronary artery disease. It does give great information about heart size, function, and generalized blood flow under physical stress but does not define the anatomy of the coronary artery system. At your age and without congenital heart disease would doubt there is a serious issue. ...Read more

Can a stress echo test pick up minimal blockage ? I am 25 years old and i got to 185 bpm...How sensitive are they?

Can a stress echo test pick up minimal blockage ? I am 25 years old and i got to 185 bpm...How sensitive are they?

No: Stress studies are designed to pick up a physiologically significant coronary obstruction (which produces a supply:demand imbalance when cardiac workload is high). This typically occurs when a coronary obstruction reaches 70% occluded in severity. ...Read more

Have a stress echo coming up. Will working out beforehand to prepare improve test results ?

Have a stress echo coming up. Will working out beforehand to prepare improve test results ?

Not recommended: Depends on your cardiovascular fitness and your overall health profile. Usually you want to be tested as close to your baseline as possible because you are exercising your heart to exhaustion. It's usually not easy and you are asked to push your heart and body to the limit to see if your heart is experiencing oxygen hunger at that level. It may also give the examiner a false resting EKG and BP. ...Read more

I felt little dizzied like passing out during my stress echo test. However all my results came normal and o2 saturation were 98-99. Is that normal?

I felt little dizzied like passing out during my stress echo test. However all my results came normal and o2 saturation were 98-99. Is that normal?

Probably OK: many people are a little anxious doing a stress echo test. Between the anxiety and the exercise some people actually hyperventilate a little during the test and this can result in the sensation of lightheadedness. ...Read more

What's the difference between a lexiscan stress test & a stress echo dobutamine test? I have had the lexiscan before.

What's the difference between a lexiscan stress test & a stress echo dobutamine test? I have had the lexiscan before.

Nuclear/ Echo stress: Lexiscan stress generally performed with nuclear isotope, which shows blood circulation(perfusion), comparing with medication lexiscan(stressing heart) and at rest. Dobutamine echo we are looking at wallmotion of heart with medication dobutamine( stressing heart )and at rest to see they show any differences to detect blockages ...Read more

Normal nuclear stress, echo, holter 2011. Normal exercise test 7/12, 12 recent ekgs normal. Worth the risk of cath to deal with ongoing chest pain?

Normal nuclear stress, echo, holter 2011. Normal exercise test 7/12, 12 recent ekgs normal. Worth the risk of cath to deal with ongoing chest pain?

Possibly: Depends on type of pain you're having. None of the mentioned tests are perfect and all have false-negatives. If typical pain, consider cath. As with any test, risks should be weighed against benefits. Discuss further with cardiologist. ...Read more

200lb, active. Rcntly, had palpitations over 4 days, ECG was 'normal'.But cardiologiest suspects av dissociation. Could this be benign or serious? Palp gone now, on event mtr.Stress echo test pending.

Palpitations: It sounds like you are receiving the correct work-up with ecg, stress echo, and event monitor. You should already have had blood tests for electrolytes, thyroid, and red blood counts. If the tests all come back normal, and your palpitations continue, then you may need to wear the event monitor longer to see if it picks up any arrhythmias.Could be serious if any associated chest pain or dizziness. ...Read more

My echocardiogram and my ECG were normal, so what are the chances of my Stress ECHO being normal If I did the test? High right?

My echocardiogram and my ECG were normal, so what are the chances of my Stress ECHO being normal If I did the test? High right?

Likely normal: It's likely to be normal but not for the reasons you list. Because you're 24, the incidence of coronary disease is very low, so your test will probably be normal. However it's entirely possible to have a nl resting echo and nl EKG and an abnormal stress echo which is specifically looking for evidence of inadequate circulation. The resting tests are relatively insensitive to that. ...Read more

Echo (Definition)

ECHO is also known as Echocardiogram. An echocardiogram (also called an echo) is a type of ultrasound test that uses high-pitched sound waves that are sent through a device called a transducer. The device picks up echoes of the sound waves as they bounce off the different parts of your heart. These echoes are turned into moving pictures of your heart that can be seen ...Read more
